I have installed sshguard but can't get it to block after lots of failed ssh password tries.
Below is (some?) of my setup.
/etc/iptables/iptables.rules
$this->bbcode_second_pass_code('', '
# Generated by iptables-save v1.4.18 on Thu Jan 1 01:43:45 1970
*filter

:OUTPUT ACCEPT [77:7148]
:sshguard - [0:0]
-A INPUT -j sshguard
COMMIT

')
/etc/iptables/ip6tables.rules
$this->bbcode_second_pass_code('', '

systemctl status sshguard.service
$this->bbcode_second_pass_code('', '

blacklist.db has something encrypted in it
/var/log/auth.log has logs in it
Can anyone please assist me with getting this to work?
Thank you
Edit:
I forgot to post /etc/ssh/sshd_config
